5.2.1 Control and Heating Problems
Problem
Controller won't
activate.
Fryer does not heat.
Probable Causes
A. Power cord is not plugged in or circuit
breaker is tripped.
B. Controller has failed.
C. Power supply component or interface
board has failed.
A. Drain valve is open.
B. Controller has failed.
C. One or more other components have
failed.
Corrective Action
A. Plug power cord in and verify that
circuit breaker is not tripped.
B. Call FASC.
C. If any of the components in the
power supply system (including the
transformer and interface board)
fail, power will not be supplied to
the controller and it will not
function. Determining which
component has failed is beyond the
scope of operator troubleshooting.
Call FASC.
A. This fryer is equipped with a drain
safety switch that prevents the
heating element from being
energized if the drain valve is not
fully closed. Verify that the drain
valve is fully closed.
B. Call FASC.
C. If the circuitry in the fryer control
system cannot determine the frypot
temperature, the system will not
allow the element to be energized
or will de-energize the element if it
is already energized. If the
contactor, element, or associated
wiring fails, the element will not
energize. Determining which
specific component is
malfunctioning is beyond the scope
of operator troubleshooting. Call
FASC.
